Title: Structural, magnetic, and superconducting properties of pulsed-laser-deposition-grown ${La}_{1.85}$ ${Sr}_{0.15}$ ${CuO}_{4}$ / ${La}_{2 / 3}$ ${Ca}_{1 / 3}$ ${MnO}_{3}$ superlattices on (001)-oriented ${LaSrAlO}_{4}$ substrates

Abstract

Epitaxial ${La}_{1.85}$ ${Sr}_{0.15}$ ${CuO}_{4}$ / ${La}_{2 / 3}$ ${Ca}_{1 / 3}$ ${MnO}_{3}$ (LSCO/LCMO) superlattices (SL) on (001)- oriented LaSrAlO₄ substrates have been grown with pulsed laser deposition (PLD) technique. Their structural, magnetic and superconducting properties have been determined with in-situ reflection high energy electron diffraction (RHEED), x-ray diffraction, specular neutron reflectometry, scanning transmission electron microscopy (STEM), electric transport, and magnetization measurements. We find that despite the large mismatch between the in-plane lattice parameters of LSCO (a = 0.3779 nm) and LCMO (a = 0.387 nm) these superlattices can be grown epitaxially and with a high crystalline quality. While the first LSCO layer remains clamped to the LSAO substrate, a sizeable strain relaxation occurs already in the first LCMO layer. The following LSCO and LCMO layers adopt a nearly balanced state in which the tensile and compressive strain effects yield alternating in-plane lattice parameters with an almost constant average value. No major defects are observed in the LSCO layers, while a significant number of vertical antiphase boundaries are found in the LCMO layers. The LSCO layers remain superconducting with a relatively high superconducting onset temperature of T_c^onset ≈ 36 K. The macroscopic superconducting response is also evident in the magnetization data due to a weak diamagnetic signal below 10 K for H ∥ ab and a sizeable paramagnetic shift for H ∥ c that can be explained in terms of a vortex-pinning-induced flux compression. The LCMO layers maintain a strongly ferromagnetic state with a Curie temperature of T^Curie ≈ 190 K and a large low-temperature saturation moment of about 3.5 (1) μ_B. These results suggest that the LSCO/LCMO superlattices can be used to study the interaction between the antagonistic ferromagnetic and superconducting orders and, in combination with previous studies on YBCO/LCMO superlattices, may allow one to identify the relevant mechanisms.
