Demonstrating magnetic memory in iron-rhodium structures using a quantum diamond microscope
Kristine V. Ung, Gregory M. Stephen, Nicholas A. Blumenschein +7
Iron-rhodium (FeRh) has a first-order phase transition near room temperature between antiferromagnetic (AFM) and ferromagnetic (FM) phases, making it a promising material for magne…
Conductivity scaling of the anomalous Hall effect in the altermagnetic semiconductor α-MnTe
Sara Bey, Shelby S. Fields, Nicholas G. Combs +22
α-MnTe is a prototypical altermagnet exhibiting a strong anomalous Hall effect (AHE), despite having a nearly vanishing magnetization. Lately, sample-to-sample variations of the a…
Facile Optimization of Combinatorial Sputtering Processes with Arbitrary Numbers of Components for Targeted Compositions
Shelby Sutton Fields, Christopher David White, Keith Knipling +1
Combinatorial sputtering is a physical vapor deposition method that enables the high-throughput synthesis of compositionally varied thin films. Using this technique, the effects of…
Anomalous low-field magnetoresistance in FeGa single crystals
Michelle E. Jamer, Gregory M. Stephen, Brandon Wilfong +6
FeGa possesses a helical spin spiral with a complex competition between ferromagnetic and antiferromagnetic ground states. This competition generates multiple metamagnetic…
Effects of altermagnetic order, strain and doping in RuO
Darshana Wickramaratne, Marc Currie, Shelby S. Fields +2
RuO, one of the most widely studied transition metal oxides, was recently predicted to host a novel form of collinear magnetic order referred to as altermagnetism. In this stud…
Probing Magnetic Properties of RuO Heterostructures Through the Ferromagnetic Layer
Frank M. Abel, Subhash Bhatt, Shelby S. Fields +20
RuO has been proposed as the prototypical altermagnetic material. However, several reports have recently questioned its intrinsic magnetic ordering, leading to conflicting fi…
