Recent Photoemission Data from Layered Manganites and Cuprates — •Zhi-xun Shen — Department of Physics, Applied Physics and Stanford Synchrotron Radiation Laboratory, Stanford University
We present recent angle-resolved photoemission data from manganites and cuprates. Despite the difference in their ground state properties, superconductivity versus ferromagnetism, these materials exhibit interesting similarity in their electronic structure. In particular, the pseudogap state in deeply underdoped curpates finds a counterpart in manganites. We will also report recent data from a new cuprate with four CuO$_2$ planes per unit cell, where we discovered a strong Fermi surface dependence of the superconducting gap.
