Claims18
A composition, comprising:
- magnetic nanoparticles having an arithmetic mean or a lognormal median physical diameter and an arithmetic mean or lognormal median magnetic diameter, wherein the arithmetic mean or lognormal median physical diameter is less than about 1 nm greater than the arithmetic mean or lognormal median magnetic diameter, wherein the arithmetic mean or lognormal median magnetic diameter has a size distribution with a coefficient of variation of about 1 to 12%, wherein the magnetic nanoparticle is SrFe12O19 or BaFe12O19.
A composition, comprising:
- magnetic nanoparticles having an arithmetic mean or a lognormal median physical diameter and an arithmetic mean or lognormal median magnetic diameter, wherein the arithmetic mean or lognormal median physical diameter is 15 to 40 nm, wherein the arithmetic mean or lognormal median magnetic diameter is less than 1 nm less than the arithmetic mean or lognormal median physical diameter, wherein the magnetic nanoparticle is MFe2O4, wherein M is Co, Zn, or Ni, or their combinations.
