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…
Anomalous magneto-optical response at van der Waals interface
Muhammad Hassan Shaikh, Abhijith Puthiya Veettil, Collin Maurtua +9
Ruthenium dioxide () has been proposed as an altermagnetic candidate, although its magnetic ground state remains controversial. Here, we probe weak interfacial magn…
Broken intrinsic symmetry induced magnon-magnon coupling in synthetic ferrimagnets
Mohammad Tomal Hossain, Hang Chen, Subhash Bhatt +5
Synthetic antiferromagnets offer rich magnon energy spectra in which optical and acoustic magnon branches can hybridize. Here, we demonstrate a broken intrinsic symmetry induced co…
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…
Revisiting altermagnetism in RuO2: a study of laser-pulse induced charge dynamics by time-domain terahertz spectroscopy
David T. Plouff, Laura Scheuer, Shreya Shrestha +7
Altermagnets are a recently discovered class of magnetic material with great potential for applications in the field of spintronics, owing to their non-relativistic spin-splitting…
