Difference on the writing Ibrahim in Quran

What is the difference between these two writings of "Ibrahim" in Quran: # إِبۡرَٰهِيمَ # # إِبۡرَٰهِـۧمَ # In the first case like we can find many in chapter 3 (ali imran), long vowel of hi (هِ) is written as a letter ya (ي) sukoon. While in the second case (many in chapter al-baqarah), long vowel of hi (هِ) is written as a diacritic. Cmiiw. Is it all by intention (related to certain meanings)? Or is it interchangable and nothing to indicate by these writings?
