Query: Superconductivity-induced Magnetic Modulation in a Ferromagnet Through
  an Insulator in LaCaMnO3\SrTiO3\YBa2Cu3O7-{\delta} Hybrid Heterostructures   Coexistence of ferromagnetic and superconducting orders and their interplay
in ferromagnet-superconductor heterostructures is a topic of intense research.
While it is well known that proximity of a ferromagnet suppresses
superconducting order in the superconductor, there exist few studies indicating
the proximity of a superconductor suppressing ferromagnetic order in a
ferromagnet. Here we demonstrate a rare observation of the suppression of
ferromagnetic order in a LaCaMnO3 layer separated from a YBa2Cu3O7-{\delta}
layer by a thin insulator (SrTiO3). Polarized neutron reflectivity measurements
on LaCaMnO3\SrTiO3\YBa2Cu3O7-{\delta} trilayer deposited on [001] SrTiO3 single
crystal substrates shows the emergence of a thin magnetic dead layer in
LaCaMnO3 adjacent to the insulating layer below its superconducting transition
temperature of YBa2Cu3O7-{\delta}. Further, the magnetic dead layer grows in
thickness when the insulating layer is made thinner. This indicates a possible
tunneling of the superconducting order-parameter through the insulating SrTiO3
inducing modulation of magnetization in LaCaMnO3.
