Using neutron diffraction, we measured the sizes of antiferromagnetic domains in three ferromagnet/antiferromagnet bilayer samples as a function of the magnitude and sign of exchange bias, temperature, and antiferromagnet ...

The critical temperature of an underdoped cuprate superconductor is limited by its phase stiffness rho. In this paper we argue that the dependence of rho on doping x should be understood as a consequence of deleterious ...
