Abstract

The spin injection effects from C-type antiferromagnetic Nd{sub 0.35}Sr{sub 0.65}MnO{sub 3} (NSMO) to superconductor YBa{sub 2}Cu{sub 3}O{sub 7−δ} (YBCO) are investigated via the measurement of temperature dependent resistivity with input current from 10{sup −2 }mA to 90 mA. The superconducting transition temperature (T{sub co}) of YBCO decreases with increasing current but at a higher rate with larger thickness of NSMO. Two spin states below T{sub co} are identified as non-equilibrium spin-state and pair-breaking state judging from the width of transition. In particular, the transition from former to later one is observed with NSMO = 30 nm at the current of 30 mA.

Lattice effects, stability under a high magnetic field, and magnetotransport properties of the charge-ordered mixed-valence La{sub 0.35}Ca{sub 0.65}MnO{sub 3} perovskite

Journal Article Ibarra, M; De Teresa, J; Blasco, J; ... - Physical Review, B: Condensed Matter

The highly Mn{sup +4}-doped compound La{sub 0.35}Ca{sub 0.65}MnO{sub 3} has been studied up to high temperature (700 K) by using thermal-expansion, magnetostriction, magnetoresistance, and neutron-diffraction techniques. From 700 K down to room temperature the electrical conduction takes place through thermally activated hopping of polarons with E{sub hop}=45 meV. At the charge-ordering (CO) transition temperature T{sub CO}=275 K, pronounced anomalies in the resistivity and the lattice are observed. The neutron thermodiffractogram clearly establishes that the CO state occurs in the paramagnetic (P) phase and is accompanied by a large anisotropic lattice distortion with a simultaneous large distortion of the MnO{sub 6}more »« less

Enhanced magnetoresistance in YBa{sub 2}Cu{sub 3}O{sub 7}/Nd{sub 0.7}Sr{sub 0.3}MnO{sub 3} heterostructures using magnetic flux focusing

Journal Article Dong, Z; Boettcher, T; Chen, C; ... - Applied Physics Letters

Enhanced low field magnetoresistance (MR) in Nd{sub 0.7}Sr{sub 0.3}MnO{sub 3} (NSMO) has been achieved by using high-{ital T}{sub {ital c}} superconducting flux focusing devices made of YBa{sub 2}Cu{sub 3}O{sub 7}(YBCO)/NSMO heterostructures. Two kinds of flux focusing schemes, gap, and washer devices, have been used where an applied magnetic field is expelled from patterned YBCO pads and focused onto a bridge of NSMO film. Using such a magnetic lens, at temperatures below 77 K {approximately}800{percent} enhancement in MR={minus}({ital R}{sub {ital H}}{minus}{ital R}{sub 0})/{ital R}{sub 0} was observed for different samples. This corresponds to more than 10{percent} change in the MR ofmore »« less

Comparative study of magnetic ordering in bulk and nanoparticles of Sm{sub 0.65}Ca{sub 0.35}MnO{sub 3}: Magnetization and electron magnetic resonance measurements

Journal Article Anuradha, K.; Bhagyashree, K.; Bhat, S. - Journal of Applied Physics

To explore the effect of size reduction to nanoscale on the hole doped Sm{sub 0.65}Ca{sub 0.35}MnO{sub 3} compound, dc magnetic measurements and electron magnetic resonance (EMR) were done on bulk and nanoparticle samples in the temperature range 10 ≤ T ≤ 300 K. Magnetization measurement showed that the bulk sample undergoes a charge ordering transition at 240 K and shows a mixed magnetic phase at low temperature. However, the nanosample underwent a ferromagnetic transition at 75 K, and the charge ordered state was destabilized on size reduction down to nanoscale. The low-temperature ferromagnetic component is found to be enhanced in nanoparticles as compared to their bulk counterpart.more »« less

Electronic structure study of wide band gap magnetic semiconductor (La{sub 0.6}Pr{sub 0.4}){sub 0.65}Ca{sub 0.35}MnO{sub 3} nanocrystals in paramagnetic and ferromagnetic phases

Journal Article Dwivedi, G.; Chou, H.; Yang, K.; ... - Applied Physics Letters

X-ray circular magnetic dichroism (XMCD), X-ray photoemission spectroscopy (XPS), and ultraviolet photoemission spectroscopy (UPS) techniques were used to study the electronic structure of nanocrystalline (La{sub 0.6}Pr{sub 0.4}){sub 0.65}Ca{sub 0.35}MnO{sub 3} near Fermi-level. XMCD results indicate that Mn{sup 3+} and Mn{sup 4+} spins are aligned parallel to each other at 20 K. The low M-H hysteresis curve measured at 5 K confirms ferromagnetic ordering in the (La{sub 0.6}Pr{sub 0.4}){sub 0.65}Ca{sub 0.35}MnO{sub 3} system. The low temperature valence band XPS indicates that coupling between Mn3d and O2p is enhanced and the electronic states near Fermi-level have been suppressed below T{sub C}.

Electron, spin-wave, hyperfine, and phonon contributions to the low-temperature specific heat of La{sub 0.65}Ca{sub 0.35}MnO{sub 3}: Effects of magnetic fields and {sup 16}O/{sup 18}O exchange

Journal Article Fisher, R; Bouquet, F; Phillips, N; ... - Physical Review B

The field-dependent low-temperature specific heat of an optimally doped polycrystalline sample of La{sub 0.65}Ca{sub 0.35}MnO{sub 3} (T{sub C}=265 K), 1{<=}T{le}32 K and 0{<=}H{le}9 T was analyzed by a global least-square fit to separate the hyperfine, electronic, spin-wave, and lattice contributions. The hyperfine and spin-wave contributions are in quantitative agreement with nuclear magnetic resonance and inelastic neutron-scattering results, respectively. This agreement supports the validity of both the data and their analysis. The calculated band-structure electron density of states is enhanced by a factor of 1.25. Specific heat was measured for two pieces cut from the {sup 16}O parent sample and processedmore »« less
