Magnetization study on the field-induced quantum critical point in YbRh_2Si_2

Y. Tokiwa, C. Geibel, F. Steglich +1

We study the field-induced quantum critical point (QCP) in YbRh${}_2$Si${}_2$ by low-temperature magnetization, $M(T)$, and magnetic Grüneisen ratio, ${\Gamma }_{\mathrm{mag}}$, measurements and co…
