The spin pumping effect in antiferromagnets, which ultimately converts THz waves into a spin current, is the key physical mechanism leading to an essential function which harnesses the THz technology and spintronics. Here, we report thorough experimental investigations of the spin current induced by the antiferromagnetic spin pumping effect in epitaxial α-Fe_{2}O_{3} thin films having two distinct dynamic modes and unambiguously show that both the inter- and intrasublattice spin mixing conductance are equally substantial. Our experimental insight is an important advance for understanding the physics of transduction between the spin current and the staggered magnetization dynamics at THz frequency.

Hypertension increases the risk of cerebrovascular disease and death. In addition to aerobic exercise, which is currently recommended for its antihypertensive effects, recent studies have suggested that dynamic and isometric resistance exercises also have antihypertensive effects. However, the magnitude of the antihypertensive effect of such resistance exercises is not well known.

The International Staging System for multiple myeloma recently underwent a second revision (R2-ISS) to include gain/amplification of 1q21 and account for the additive prognostic significance of multiple high-risk features. The phase 3 ICARIA-MM (isatuximab-pomalidomide-dexamethasone vs. pomalidomide-dexamethasone) and IKEMA (isatuximab-carfilzomib-dexamethasone vs.

Article Synopsis
  • Singlet fission (SF) is a process that turns one singlet exciton into two triplet excitons, which can enhance energy transfer in materials.
  • The study explored SF dynamics in specific linear heterotrimer systems made from different pentacene derivatives to understand how substituents affect exciton behavior.
  • The findings suggest that appropriate substituent choices can significantly increase the efficiency of triplet exciton migration due to quantum interference effects that emerge from reduced structural symmetry.
