Scientific Highlights
Realizing Blume-Capel Degrees of Freedom with Toroidal Moments in a Ruby Artificial Spin Ice
Realizing exotic Hamiltonians beyond the Ising model is a key pursuit in experimental statistical physics. Onesuch example is the Blume-Capel model, a three-state spin model, whose phase diagram features a tricritical point where second-order and first-order transition lines converge, leading to a coexistence of paramagnetic, ferromagnetic, and disordered phases. Here, we realize ...
Two-dimensional gradients in magnetic properties created with direct-write laser annealing
Across the fields of magnetism, microelectronics, optics, and others, engineered local variations in material properties can yield groundbreaking functionalities that play a crucial role in enabling future technologies. One-dimensional lateral gradients in material properties give rise to a plethora of new effects in thin-film magnetic systems. However, extending such gradient-induced behaviors to two dimensions has been challenging to realize experimentally. Here, we demonstrate the creation of two-dimensional complex patterns with continuous variations in magnetic anisotropy, interlayer exchange coupling, and ferrimagnetic compensation at the mesoscopic scale in numerous application-relevant magnetic materials. We exploit our engineered gradients in material properties to demonstrate novel magnetic functionalities, including the creation of a spin wave band pass filter and an architecture for passively resetting the position of a magnetic domain wall. Our results highlight the exciting new physics and device applications enabled by two-dimensional gradients in thin film properties.
Coexistence of Insulatorlike Paramagnon and Metallic Spin-Orbit Exciton Modes in SrIrO3
We probe the spectrum of elementary excitations in SrIrO3 by using heterostructured [(SrIrO3)m / (SrTiO3)l] samples to approach the bulk limit. Our resonant inelastic x-ray scattering (RIXS) measurements at the Ir L3 edge reveal ...

Laser draws made-to-order magnetic landscapes
Researchers at the Paul Scherrer Institute PSI, in collaboration with the National Institute of Standards and Technology (NIST) in Boulder, Colorado, have for the first time succeeded in using existing laser technology to continuously vary the magnetic properties of two-dimensional materials. This simple and fast method should make a large number of applications possible, including techniques for data storage and processing.
