Local magnetic order in vacancy-disrupted spin ice Ho2TiO5
Raju Baral, Haidong Zhou, Qiang Zhang +2
We investigate how local magnetic correlations evolve when the classical pyrochlore spin-ice Ho2Ti2O7 is transformed into the partially disordered stuffed compound Ho2TiO5. Neutron…
Correlation-Driven Spin Reorientation via Competing Anisotropy Channels in CrPS4
Raju Baral, Harald O. Jeschke, Igor I. Mazin +3
We identify a correlation-driven mechanism for the temperature-induced spin reorientation in the quasi-one-dimensional van der Waals antiferromagnet CrPS4. Magnetic pair distributi…
