Hybrid dynamic systems have recently gained interest with respect to both fundamental
physics and device applications, particularly with their potential for coherent information …

Superconductivity (SC) and ferromagnetism (FM) are normally antagonistic, and their
coexistence in a single crystalline material appears to be very rare. Over a decade ago, the …

In pnictide RbEuFe4As4, superconductivity sets in at 36 K and coexists, below 15–19 K, with
the long-range magnetic ordering of Eu 4f spins. Here we report scanning tunneling …

Magnetic excitations and magnetic structure of EuRbFe 4 As 4 were investigated by inelastic
neutron scattering (INS), neutron diffraction, and random phase approximation (RPA) …

In this Letter, we describe quantitative magnetic imaging of superconducting vortices in
RbEuFe 4 As 4 in order to investigate the unique interplay between the magnetic and …

In the new stoichiometric high-temperature ironbased superconductor RbEuFe4As4,
superconductivity coexists with a peculiar long-range magnetic order of the Eu 4f states; …

Recently, a colossal magnetoresistance (CMR) was observed in Eu Cd 2 P 2, a compound
that does not fit the conventional mixed-valence paradigm. Instead, experimental evidence …

Recently the evidence of the helical magnetic structure modulated along the c axis with the
period of four lattice parameters was obtained in easy ab plane ferromagnetic …

We study single crystals of the magnetic superconductor Eu Rb Fe 4 As 4 by magnetization,
electron spin resonance (ESR), angle-resolved photoemission spectroscopy, and electrical …

Motivated by the recent discovery of helical magnetic structure in RbEuFe 4 As 4, we
investigate interlayer ordering of magnetic moments in materials composed of spatially …
