Compounds of general formula ABO3 are widely studied due to their versatility regarding chemical composition, structure and physical properties. The use of high-pressure and high-temperature synthesis method allows the introduction of small Mn 2+ cation into the often-large A site, giving rise to the so-called Asite manganites, with a few exceptions to this rule. Polymorphism, structural features and magnetic properties of A-site manganites are revisited in this short review dedicated to Miguel A. Alario y Franco on his 80 th birthday. We extend this dedication to John B. Goodenough and J. Paul Attfield on their 100 th and 60 th birthdays in recognition of their ground work. Happy birthday all three!
