Abstract:
We report the results of a study of the differential magnetic
susceptibility of Sr3Ru2O7 as a function of temperature and magnetic
fields applied at a series of angles to the ab plane. By analyzing the
real and imaginary parts of the susceptibility, we conclude that the
field angle acts as a continuous tuning parameter for the critical end
point to a line of first-order metamagnetic phase transitions. The end
point sits at approximate to1.25 K for fields applied in the ab plane,
and is depressed to below 50 mK when the field is aligned within
10degrees of the c axis.
