Yttrium Manganate, YMnO3
Yttrium manganate (YMnO3) sputtering targets are dense ceramic sources used to deposit multiferroic thin films that combine ferroelectric and antiferromagnetic order in a single material. Infinita Materials supplies YMnO3 targets at >99.9% purity in catalog sizes (1″ dia. × 0.125″ thick, 2″ dia. × 0.25″ thick) and custom dimensions, for spintronics, memory-device, and sensor research and production.

Introduction to Yttrium Manganate
Yttrium manganate is a hexagonal rare-earth manganite that crystallises in the polar P6₃cm space group at room temperature. It is one of the most widely studied multiferroic materials: below its ferroelectric transition (roughly 900–920 K) it carries a stable spontaneous polarisation, while below its Néel temperature of about 70 K its Mn³⁺ ions order into a geometrically frustrated triangular-lattice antiferromagnetic structure. The coexistence and coupling of these two order parameters is what makes YMnO3 a reference material for magnetoelectric research.
Sputtering is one of the primary routes for depositing YMnO3 as an epitaxial or polycrystalline thin film while preserving its crystallinity, stoichiometry, and multiferroic response, making the sputtering target the key consumable for this class of device research. Infinita Materials fabricates YMnO3 targets in catalogue dimensions or fully custom sizes, with purity and target format matched to the deposition system and required film performance.
FAQs
Question: What is yttrium manganate used for as a thin film?
Answer: Sputtered YMnO3 films are used to study and develop magnetoelectric memory, multiferroic MRAM concepts, magnetic and electric field sensors, and related spintronic and energy-storage device structures, where the film's coupled ferroelectric and antiferromagnetic order is the property of interest.
Question: Can YMnO3 targets be sputtered with DC power?
Answer: YMnO3 is a semiconducting oxide, so RF, RF-reactive, and DC or pulsed-DC magnetron sputtering are all used depending on target resistivity and tool configuration; RF or RF-reactive is the most broadly compatible choice.
Question: What target sizes are available?
Answer: Standard catalog research targets are offered at 1″ diameter × 0.125″ thick and 2″ diameter × 0.25″ thick. We can produce larger custom diameters, rectangular/block formats, and bonded assemblies for scaled-up or production sputtering.
