Title: Helical magnetism in Sr-doped $CaM n_{7} O_{12}$ films

Abstract

Noncollinear magnetism can play an important role in multiferroic materials but is relatively understudied in oxide heterostructures compared to their bulk counterparts. Using variable temperature magnetometry and neutron diffraction, we demonstrate the presence of helical magnetic ordering in CaMn₇O₁₂ and Ca_1-xSr_xMn₇O₁₂ (for x up to 0.51) thin films. Consistent with bulk Ca_1-xSr_xMn₇O₁₂, the net magnetization increases with Sr doping. Neutron diffraction confirms that the helical magnetic structure remains incommensurate at all values of x, while the fundamental magnetic wavevector increases upon Sr substitution. Lastly, this result demonstrates a chemical-based approach for tuning helical magnetism in quadruple perovskite films and enables future studies of strain and interfacial effects on helimagnetism in oxide heterostructures.

Perpendicular magnetic anisotropy (PMA) in multilayer thin films promotes the development of spintronic and magnonic research fields. The origin of the PMA deserves a thorough investigation since it contains rich physics related to multiple factors in the heterostructure system. In this report, we study the origin of PMA in La_2/3Sr_1/3 Mn O₃ (LSMO) thin films sandwiched by La_1-xSr_xCoO_3-δ (LSCO) layers grown on SrTiO₃ substrate, using aberration-corrected scanning transmission electron microscopy. Our findings indicate that the lattice and electronic structures of LSMO can be modified through the inhomogeneous strains induced by nanodomains in LSCO layers. Moreover, we infer that the latticemore »« less

We report the synthesis of millimeter-sized freestanding single-crystal YBa₂Cu₃O_7–x heterostructure membranes with nanoscale thickness. On a SrTiO₃ substrate, a heteroepitaxial water-soluble sacrificial layer of Sr₃Al₂O₆ followed by an encapsulated YBa₂Cu₃O_7–x film is grown by pulsed laser deposition. A freestanding YBa₂Cu₃O_7–x heterostructure membrane is obtained by etching the sacrificial layer. As a result, its high crystalline quality is demonstrated via x-ray diffraction, electrical measurements, and scanning transmission electron microscopy.

We report the results of magnetization measurements with the magnetic field applied along the c axis on superconducting La_1.9Ca_1.1Cu₂O_6+δ single crystals processed under ultrahigh oxygen pressure. Strong fluctuation effects were found in both low- and high-field regimes. Scaling analysis of the high-field magnetization data near the critical temperature (T_c = 53.5K) region reveals the characteristics of critical fluctuation behavior of quasi-two-dimensional (2D) superconductivity, described by Ginzburg-Landau theory using the lowest Landau level approximation. Low-field magnetic susceptibility data can be successfully explained by the Lawrence-Doniach model for a quasi-2D superconductor, from which we obtained the a b plane Ginzburg-Landau coherence lengthmore »« less
