Phonon-mediated strong coupling between a three-dimensional topological insulator and a two-dimensional antiferromagnetic material
D. Quang To, Weipeng Wu, Subhash Bhatt +8
Van der Waals antiferromagnetic and topological insulator materials provide powerful platforms for modern optical, electronic, and spintronic devices applications. The interaction…
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…
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…
Rare earth size dependence on structural, electronic and magnetic properties of R2NiMnO6 double perovskites
Mohd Nasir, Sunil Kumar, N. Patra +8
Rare earth Manganite Nickelite double perovskites are prepared by solgel assisted combustion route, where, R varies from La, Pr, Nd, Sm, Gd, Tb, Dy, Y, and Ho. The samples have bee…
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…
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…
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…
