Evidence of Weyl Fermion Enhanced Thermal Conductivity Under Magnetic Fields in Antiferromagnetic Topological Insulator Mn(Bi(1-x)Sb(x))2Te4
Robert A. Robinson, Seng Huat Lee, Lujin Min +3
We report thermal conductivity and Seebeck effect measurements on Mn(Bi1-xSbx)2Te4 (MBST) with x = 0.26 under applied magnetic fields below 50 K. Our data shows clear indications o…
Large Violation of the Wiedemann Franz Law in Heusler, Ferromagnetic, Weyl Semimetal CoMnAl
Robert A. Robinson, Lujin Min, Seng Huat Lee +4
The Wiedemann-Franz (WF) law relates the electronic component of the thermal conductivity to the electrical conductivity in metals through the Lorenz number. The WF law has proven…
Giant spin-valve effect and chiral anomaly in antiferromagnetic topological insulators Mn(Bi1-xSbx)2Te4
Seng Huat Lee, David Graf, Robert Robinson +3
We report c-axis transport studies on magnetic topological insulators Mn(Bi1-xSbx)2Te4. We performed systematic c-axis magnetoresistivity measurements under high magnetic fields (u…
Giant shifts of crystal-field excitations with temperature as consequence of internal magnetic exchange fields
Joel O'Brien, Guochu Deng, Dehong Yu +7
Crystal-field excitations, for example in transition-metal oxides where a rare-earth element is used as a spacer between the transition-metal-oxide tetrahedra and octahedra, are as…
Tunneling of the Mn12-acetate spin cluster
Wei bao, R. A. Robinson, J. R. Friedman +3
The term in spin Hamiltonian, which determines the quantum tunneling rate in Mn12, is measured with neutron scattering. It is much smaller than previously reported values. This may…
