Peculiarities of the electron spin resonance in heavy fermion compounds: theory and experiment

  VolkswagenStiftung

Duration: 2009 – 2012

Grant amount: 63000 EUR

Objectives: Theoretical and experimental investigations of the EPR phenomenon at low temperatures. 

The main task of the project is to reveal the nature of the EPR signal in heavy electron systems.
