Collapse of Jahn-Teller Phonons in LaSrMnO with Weak Magnetoresistance
Tyler C. Sterling, Andrei T. Savici, Ryoichi Kajimoto +4
Perovskite manganites are quantum materials exhibiting competing interactions inducing colossal magnetoresistance (CMR). The prevailing theory of CMR highlights the essential role…
A combined inelastic neutron scattering and \textit{ab initio} lattice dynamics study of FeSi
Nazir Khan, Sven Krannich, Dominic Boll +5
The phonon renormalization across the semiconductor-to-metal crossover in FeSi is investigated by inelastic neutron scattering combined with \textit{ab-initio} lattice dynamical ca…
Complex exchange mechanism driven ferromagnetism in half-metallic Heusler CoTiGe: Evidence from critical behavior
Shubhankar Roy, Nazir Khan, Ratnadwip Singha +2
We have investigated the critical phenomenon associated with the magnetic phase transition in the half-metallic full-Heusler CoTiGe. The compound undergoes a continuous ferroma…
Giant magnetocaloric effect in exchange-frustrated GdCrTiO5 antiferromagnet
M. Das, S. Roy, N. Khan +1
We report the effect of exchange frustration on the magnetocaloric properties of GdCrTiO compound. Due to the highly exchange-frustrated nature of magnetic interaction, in GdCr…
Collapse of ferromagnetism with Ti doping in SmSrMnO: A combined experimental and theoretical study
P. Sarkar, N. Khan, K. Pradhan +1
We have investigated the effect of Ti doping on the transport properties coupled with the magnetic ones in SmSrMnTiO (). The pa…
