Effect of pressure on first-order valence transition of Yb 1- xY xInCu 4
Abstract
YbInCu 4 exhibits a first-order valence transition at H v≈33 T with 0.45% decrease of volume as increasing the magnetic field. The inherent chemical pressure in Yb 1- xY xInCu 4 system is discussed as negative on valence transition of YbInCu 4. The external pressure effect on Hv of Yb 1- xY xInCu 4 is measured as dH v/ dP≈-1 T kbar -1.
