  Magnetic-field-resilient superconducting coplanar waveguide (SCPW) resonators
are essential for developing integrated quantum circuits of various qubits and
quantum memory devices. Molybdenum-Rhenium (MoRe), which is a disordered
superconducting alloy forming a highly transparent contact to the graphene and
carbon nanotubes (CNTs), would be a promising platform for realizing the
field-resilient SCPW resonators combined with graphene- and CNT-based
nano-hybrid qubits. We fabricated MoRe SCPW resonators and investigated their
microwave transmission characteristics with varying temperature and external
magnetic field. Our observations show that the thickness of MoRe film is a
critical parameter determining the lower critical field, kinetic inductance,
and characteristic impedance of the SCPW resonator, resulting in drastic
changes in the quality factor and the resonance frequency. As a result, we
obtained a maximum value of $Q_{i} > 10^{4}$ in parallel magnetic fields up to
$B_{||} = 0.15$ T for the 27-nm-thick MoRe resonator. Our experimental results
suggest that MoRe SCPW resonator would be useful for integrating nano-hybrid
spin or gatemon qubits and for developing spin-ensemble quantum memory devices.
