DESCRIPTION:Caloric effects in magnetic materials have generated a lot of i
 nterest in the scientific community over the years owing to their impact o
 n technological applications such as refrigeration\, waste heat recovery f
 or power generation\, thermoelectric and spintronic devices. There are man
 y caloric effects generally related to the coupling of ferroic order param
 eters to external magnetic fields and phase transitions or generation and 
 manipulation of pure spin currents through thermal gradients. In this talk
  we would focus on two such caloric effects namely the magnetocaloric effe
 ct (MCE) and spin caloric effect (SCE) and present recent advances on thes
 e topics made in our Functional Materials Laboratory. We demonstrate that 
 it is possible to combine thermoelectric and magnetocaloric properties for
  dual functional refrigeration in Eu8Ga16Ge30 semiconducting clathrates. B
 y forming composites with EuO we can tune the optimal MCE characteristics\
 , operating temperature range and refrigerant capacity. In the other area 
 of spin caloritronics\, we emphasize the important role of magnetic anisot
 ropy and interface coupling between the magnetic insulator (YIG) and metal
  (Pt) layers through systematic investigations of the anisotropy and spin 
 Seebeck effect (SSE). We discuss the exciting possibility of improving the
  spin mixing conductance and enhancing SSE through appropriate choice of b
 uffer layers between YIG and Pt. Overall\, we will present an overview bas
 ed on our research how these caloric effects can lead to new and improved 
 thermomagnetic devices.\n\nCo-sponsored by: UCCS\n\nSpeaker(s): Hari Srika

X-ALT-DESC:Description: <br /><p style="text-align: justify\;">Caloric effe
 cts in magnetic materials have generated a lot of interest in the scientif
 ic community over the years owing to their impact on technological applica
 tions such as refrigeration\, waste heat recovery for power generation\, t
 hermoelectric and spintronic devices. There are many caloric effects gener
 ally related to the coupling of ferroic order parameters to external magne
 tic fields and phase transitions or generation and manipulation of pure sp
 in currents through thermal gradients. In this talk we would focus on two 
 such caloric effects namely the magnetocaloric effect (MCE) and spin calor
 ic effect (SCE) and present recent advances on these topics made in our Fu
 nctional Materials Laboratory. We demonstrate that it is possible to combi
 ne thermoelectric and magnetocaloric properties for dual functional refrig
 eration in Eu8Ga16Ge30 semiconducting clathrates. By forming composites wi
 th EuO we can tune the optimal MCE characteristics\, operating temperature
  range and refrigerant capacity. In the other area of spin caloritronics\,
  we emphasize the important role of magnetic anisotropy and interface coup
 ling between the magnetic insulator (YIG) and metal (Pt) layers through sy
 stematic investigations of the anisotropy and spin Seebeck effect (SSE). W
 e discuss the exciting possibility of improving the spin mixing conductanc
 e and enhancing SSE through appropriate choice of buffer layers between YI
 G and Pt. Overall\, we will present an overview based on our research how 
 these caloric effects can lead to new and improved thermomagnetic devices.
