      Direct magnetocaloric measurements of Fe-B-Cr-X (X = La, Ce) amorphous ribbons  [Article]

      Law, Jia Yan; Franco García, Victorino; Ramanujan, Raju Vijayaraghavan (American Institute of Physics, 2011)
      A procedure has been developed to directly measure the adiabatic temperature change of amorphous melt-spun Fe-based ribbons displaying attractive room temperature magnetocaloric properties. Polycrystalline Gd ribbons are ...

      Influence of La and Ce additions on the magnetocaloric effect of Fe–B–Cr-based amorphous alloys  [Article]

      Law, Jia Yan; Franco García, Victorino; Ramanujan, Raju Vijayaraghavan (American Institute of Physics, 2011)
      The magnetic entropy change (ΔSM), temperature of peak ΔSM (Tpk) and refrigerant capacity (RC) in Fe(RE)80B12Cr8 (RE = La, Ce, or Gd) alloys were studied. Increasing La, Ce, and Gd content led to relatively constant, ...

      Low hysteresis and large room temperature magnetocaloric effect of Gd 5Si2.05-xGe1.95-xNi2x (2x 0.08, 0.1) alloys  [Article]

      Franco García, Victorino; Zhong, Xichun; Min, J. X.; Liu, Z. W.; Zheng, Zhigang; Zeng, Dechang; Ramanujan, Raju Vijayaraghavan (AIP Publishing, 2013-03-18)
      Gd5Si2.05-xGe1.95-xNi2x (2x ¼ 0.08, 0.1) alloys were prepared by arc melting followed by annealing at 1273 K for 96 h. Mixed monoclinic Gd5Si2Ge2-type phase, orthorhombic Gd5Si4-type phase, and a small amount of Gd5Si3-type ...

      The magnetocaloric effect of partially crystalline Fe-B-Cr-Gd alloys.  [Article]

      Law, Jia Yan; Franco García, Victorino; Ramanujan, Raju Vijayaraghavan (AIP Publishing, 2012)
      The influence of annealing temperature and crystallization on the magnetocaloric effect (MCE) of Fe-B-Cr-Gd partially crystalline alloys was studied. Although the alloys exhibited dissimilar devitrification behavior, all ...
