Magnolia officinalis

Magnolia officinalis (厚朴, houpo), Houpu magnolia, is a Chinese magnolia tree whose bark yields the neolignans magnolol and honokiol; used in traditional medicine, endangered in the wild, preclinical anti-Alzheimer's activity.

Magnolia Oil & Gas

Magnolia Oil & Gas Corporation is a Houston-based independent oil and gas exploration and production company targeting the Eagle Ford Shale and Austin Chalk formations in South Texas.

Magnoliaceae

Magnoliaceae, the magnolia family, is a magnoliid flowering plant family with two genera, Magnolia and Liriodendron, over 300 species in Asia and the Americas, spirally arranged tepaloid flowers, beetle pollination, and many threatened species.

Magnoliales

Magnoliales is an order of magnoliid flowering plants with six APG IV families (Annonaceae, Magnoliaceae, Myristicaceae, Degeneriaceae, Eupomatiaceae, Himantandraceae), about 3,000 species, Cretaceous fossils, and crown age 164–115 Myr.

Magnolol

Magnolol is a dimeric phenolic neolignan (C18H18O2) and a primary active component of Magnolia officinalis bark, used in Chinese and Japanese herbal medicine and studied for anti-inflammatory, antitumor, and neuroprotective effects.

Magnon

A magnon is the quantum of a spin wave, the collective wavelike disturbance of aligned spins in a magnetically ordered solid; carrying spin but no electric charge, it underlies magnonics.

Magnon polarons

A magnon polaron is a hybrid quasiparticle formed when a magnon and a phonon couple through magnetoelastic interaction, marked by an anticrossing in their dispersion relations.

Magnon spin Nernst effect

The magnon spin Nernst effect is the generation of a transverse pure spin current carried by magnons when a temperature gradient is applied to a magnetic material.

Magnon transistor

A magnon transistor is a three-terminal device that controls the flow of magnons, the quasiparticles of spin waves, first demonstrated in 2014 in yttrium iron garnet by Chumak, Serga, and Hillebrands.

Magnon valleytronics

Magnon valleytronics is a research field that encodes information in the valley index of magnons, combining magnonics with valleytronics; a magnon valley Hall effect was reported in CrI3 in 2020.

Magnon valve

A magnon valve is a three-layer spintronic device, typically YIG/Au/YIG, whose magnon current is transmitted or attenuated depending on the magnetization alignment of two magnetic layers.

Magnon–qubit strong coupling

Magnon–qubit strong coupling is the regime where a magnon coherently exchanges energy with a qubit, first demonstrated in 2014 using a YIG sphere in a microwave cavity.

Magnonics

Magnonics is the field of physics and engineering concerned with generating, propagating, manipulating, and detecting spin waves and their quanta, magnons, in magnetically ordered materials, promising low-power computing.

Magnora Data Center

Magnora Data Center ASA is a Nordic data center project developer spun off from Norway's renewable-energy group Magnora ASA, listed on Euronext Growth Oslo in June 2026.

Magnox
