DESCRIPTION:B20 transition metal compound MnSi presents a model system to 
 study weak itinerant ferromagnetism. The competition of various energy sca
 les in such a system leads to the formation of a unique helimagnetic order
 . MnSi undergoes a transition into helical magnetic state at temperatures 
 below TN = 30K. The application of a magnetic field has already produced s
 ome intriguing results in the discovery of novel magnetic dynamical states
  and magnetic transport phenomena.\n\nIn this work we present a high-press
 ure study of the thermal transport properties on single crystal MnSi. In p
 articular\, the results for the thermopower and electrical resistivity are
  presented over a broad range of pressures up to 100kbar. The findings are
  discussed and compared to chemical doping studies in FexMn1-xSi within th
 e framework of spin-fluctuations. \n \n
