Marvin
Antonoff performs research in the area of condensed matter physics. His
work includes the theory of spin-wave excitations (magnons) in
ferromagnetic metals and the theory of phase transitions in the
spin-density-wave (SDW) system of transition metals. Theoretical work
in this area is part of the larger subject of quantum statistical
mechanics. The phase transition into the SDW state involves the
condensation of electron-hole pairs, similar to the transition which
takes place into the BCS superconducting state. One aspect of Professor
Antonoff’s work in this area is focused on the effect of
paramagnetic impurities on the electron-hole pairing. Magnetic
impurities may both enhance and abate the formation of the SDW state
and has proved to be useful in interpreting the data obtained in
neutron scattering of transition metal alloys. Professor Antonoff has
also studied the effect of phonons on the phase transitions in magnetic
metals. |
