Title: Magnetoresistance manipulation and sign reversal in Mn-doped ZnO nanowires

Abstract

We report magnetoresistance (MR) manipulation and sign reversal induced by carrier concentration modulation in Mn-doped ZnO nanowires. At low temperatures positive magnetoresistance was initially observed. When the carrier concentration was increased through the application of a gate voltage, the magnetoresistance also increased and reached a maximum value. However, further increasing the carrier concentration caused the MR to decrease, and eventually an MR sign reversal from positive to negative was observed. An MR change from a maximum positive value of 25% to a minimum negative value of 7% was observed at 5 K and 50 KOe. The observed MR behavior was modeled by considering combined effects of quantum correction to carrier conductivity and bound magnetic polarons. Finally, this work could provide important insights into the mechanisms that govern magnetotransport in dilute magnetic oxides, and it also demonstrated an effective approach to manipulating magnetoresistance in these materials that have important spintronic applications.

Negative to positive magnetoresistance and magnetocaloric effect in Pr_0.6Er_0.4Al₂

Journal Article Pathak, Arjun K. ; Gschneidner, Jr., K. A. ; Pecharsky, V. K. - Journal of Alloys and Compounds

We report on the magnetic, magnetocaloric and magnetotransport properties of Pr_0.6Er_0.4Al₂. The title compound exhibits a large positive magnetoresistance (MR) for H ≥ 40 kOe and a small but non negligible negative MR for H ≤ 30 kOe. The maximum positive MR reaches 13% at H = 80 kOe. The magnetic entropy and adiabatic temperature changes as functions of temperature each show two anomalies: a broad dome-like maximum below 20 K and a relatively sharp peak at higher temperature. As a result, observed behaviors are unique among other binary and mixed lanthanide compounds.

Magnetoresistance in Mn ion-implanted GaAs:Zn nanowires

Journal Article Paschoal, W. ; Kumar, Sandeep ; Jain, V. ; ... - Applied Physics Letters

We have investigated the magnetoresistance (MR) in a series of Zn doped (p-type) GaAs nanowires implanted with different Mn concentrations. The nanowires with the lowest Mn concentration (∼0.0001%) exhibit a low resistance of a few kΩ at 300 K and a 4% positive MR at 1.6 K, which can be well described by invoking a spin-split subband model. In contrast, nanowires with the highest Mn concentration (4%) display a large resistance of several MΩ at 300 K and a large negative MR of 85% at 1.6 K. The large negative MR is interpreted in terms of spin-dependent hopping in a complex magnetic nanowire landscapemore »« less

Large magnetoresistance and Fermi surface study of Sb₂Se₂Te single crystal

Journal Article Shrestha, K. ; Marinova, V. ; Graf, D. ; ... - Journal of Applied Physics

Here, we have studied the magnetotransport properties of a Sb₂Se₂Te single crystal. Magnetoresistance (MR) is maximum when the magnetic field is perpendicular to the sample surface and reaches a value of 1100% at B = 31 T with no sign of saturation. MR shows Shubnikov de Haas (SdH) oscillations above B = 15 T. The frequency spectrum of SdH oscillations consists of three distinct peaks at α = 32 T, β = 80 T, and γ = 117 T indicating the presence of three Fermi surface pockets. Among these frequencies, β is the prominent peak in the frequency spectrum of SdH oscillations measured at different tilt angles of the sample with respect to the magnetic field. From the angle dependence β and Berry phase calculations, we have confirmed the trivial topology of the β-pocket. The cyclotron masses of charge carriers, obtained by using the Lifshitz–Kosevich formula, are found to be mmore »« less

Positive giant magnetoresistance in ferrimagnetic/Cu/ferrimagnetic films

Journal Article Lai, Chih-Huang ; Lin, Chao-Cheng ; Chen, B M ; ... - Journal of Applied Physics

Spin valves composed of ferrimagnetic/Cu/ferrimagnetic layers were fabricated with the magnetization perpendicular to the film planes. By changing the composition of ferrimagnetic layers, both negative and positive giant magnetoresistance (GMR) can be observed in ferrimagnetic spin valves. For samples consisting of both transition-metal (TM-) rich TbFeCo and GdFeCo, negative GMR values were obtained. Due to the high resistivity of amorphous ferrimagnetic films, the shunting effect of Cu led to relatively small MR ratio. The negative MR effect was 1% for 1.7 nm Cu. For spin valves consisting of rare-earth (RE-)rich TbFeCo and TM-rich GdFeCo, positive GMR values were observed. Amore »« less

Colossal Magnetoresistance of Layered Manganite La{sub 1.2}Sr{sub 1.8}Mn{sub 2}O{sub 7} and Its Description by a “Spin–Polaron” Conduction Mechanism

Journal Article Gudin, S. A., E-mail: gudin@imp.uran.ru ; Solin, N. I. ; Gapontseva, N. N. - Physics of the Solid State

The resistance of a La{sub 1.2}Sr{sub 1.8}Mn{sub 2(1–z)}O{sub 7} single crystal has been studied in magnetic fields from 0 to 90 kOe. The magnetoresistance at temperature T = 75 K, near which a colossal magnetoresistance maximum is observed, has been successfully described in terms of the “spin–polaron” electric conduction mechanism. This value of the colossal magnetoresistance is due to a three-fold increase in the polaron size. The method of separating contributions of various conduction mechanisms to the magnetoresistance developed for materials with activation type of conduction is generalized to compounds in which a metal–insulator transition is observed. It is foundmore »« less
