Competing ferromagnetic and antiferromagnetic interactions in non-altermagnetic RuCrO
David T. Plouff, Nawsher J. Parvez, Subhash Bhatt +4
We investigate the proposal of hole doping RuO via alloying with Cr ions to induce altermagnetism. Thin film samples of RuCrO () were…
Magnetoresistive Memory in the Paramagnetic Phase of EuInAs
Sudhaman R. Balguri, Mira B. Mahendru, Rourav Basak +9
Magnetoresistive materials that respond sensitively to applied fields are central to modern data storage technologies. Here we unveil a novel Magnetoresistive Memory (MRM) in Eu$_5…
Disorder-induced proximate quantum spin ice phase in Pr2Sn2O7
Yi Luo, Brenden R. Ortiz, Miles J. Knudtson +9
Magnetic pyrochlores with non-Kramers rare-earth ions provide a platform for exploring emergent gauge physics and quantum spin-ice behavior, yet the influence of structural disorde…
Dynamical moment fragmentation in the all-in all-out pyrochlore Nd2Sn2O7
Yi Luo, Matthew S. Powell, Joseph A. M. Paddison +4
We report single-crystal neutron spectroscopy and bulk characterization on hydrothermally grown Nd2Sn2O7, revealing a dynamical moment fragmentation embedded within the all-in-all-…
Influence of controlled disorder on the dipolar spin ice state of Ho-based pyrochlores
A. A. Aczel, B. R. Ortiz, Y. Luo +8
Pyrochlore magnets of the form O, in which rare-earth ions on the -site form a three-dimensional network of corner-sharing tetrahedra, provide a canonical setting fo…
Vanishing ordered moment in the frustrated triangular lattice antiferromagnet CuNdO
Jonathan Gaudet, Dalmau Reig-i-Plessis, Bogeng Wen +9
We investigate the magnetic ground state of CuNdO, which is a delafossite with a triangular lattice of magnetic Nd ions that are well separated by non-magnetic Cu spacer…
