The spontaneous magnetic orders arising in ferro-, ferri-and antiferromagnets stem from
various magnetic interactions. Depending on the interplay and competition among the …

Over the past four decades, energy microsources based on piezoelectric energy harvesting
have been intensively studied for applications in autonomous sensor systems. The research …

More than twenty years ago, multiferroic compounds combining in particular magnetism and
ferroelectricity were rediscovered. Since then, BiFeO 3 has emerged as the most …

Magnons can transfer information in metals and insulators without Joule heating, and
therefore are promising for low-power computation. The on-chip magnonics however suffers …

The recent thrust in ultrafast magnetization dynamics aims at extending spintronic
functionalities to terahertz frequencies. Deterministic manipulation of magnetization at the …

Hematite (α-Fe 2 O 3) is an antiferromagnetic material with a very low spin damping and
high Néel temperature. The temperature dependence of the antiferromagnetic resonance in …

Strong coupling of electromagnetic cavity fields with antiferromagnetic spin waves in
hematite (α-Fe 2 O 3) is achieved above room temperature. A cube of hematite is placed in a …

We report the magnetic-field dependence of the THz absorption and nonreciprocal
directional dichroism spectra of Bi Fe O 3 measured on the three principal crystal cuts for …

Coupling of spin waves with electromagnetic cavity field is demonstrated in an
antiferromagnet, dysprosium ferrite (DyFeO 3). By measuring transmission at 0.2–0.35 THz …

Although BiFeO 3 is one of the most studied multiferroic materials, recent magnetization and
neutron scattering studies have revealed a new magnetic phase in this compound—the …
